Abc News – Man journeys from living under a bridge to Boston Marathon

Whether solo, jogging in a crowd, or lost in the sensation of music thumping through his headphones, Danny Dwyer sees his thorny past, thankful present and unwritten future blend to form the perfect sanctuary.

This is how he trains for this year’s Boston Marathon.

Each step is one away from battles with drug addiction that began when he was 8 years old. It’s a struggle that’s swallowed up a coveted job with the Boston Police Department and an engagement. For four years, he lived under a bridge. Now, he’s rededicated his life to helping others who struggle with substance abuse.
